Localization of BMP15 and GDF9 in calf and cow follicles. BMP15 and GDF9 immunoreactivity found in oocyte and cumulus cells of calf (A, C) and cow (B, D) follicles. BMP15 and GDF9 proteins were staining brown by immunostain using BMP15 and GDF9 antibody (A,B and C,D) or preimmuno serum with diluent (negative control; E, F). The scale bar is 100 μm.
